This invention relates to a gauge for setting the blanket and plate cylinders of a printing press, the general object of the invention being v,to provide a resilient member having a liquid containing chamber therein,` a sight gauge in communication with the chamber so that when the member is compressed by relative movement of two cylinders between which the member is placed some of the liquid will be forced into the sight gauge to accurately indicate the distance between the cylinders.

Another object of the invention is to provide adjustable means for regulating the distance the member is inserted between the cylinders and to place the iiexible member between walls of flexible metal which are engaged by the cylinders.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is an elevational View showing the device in use as measuring the space between a pair of cylinders.

Figure 2 is a longitudinal through the device.

Figure 3 is a longitudinal sectional View through the body of the device, the section being taken at right angles to that shown in Figure 2.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 5 5 of Figure 3.

Figure 6 is a top plan View of the means for regulating the extent of insertion of the device between a pair of cylinders.

In this drawing the numeral I indicates an elongated member of rubber or the like and of substantially rectangular shape in cross section and which is provided with a longitudinally extending elongated chamber 2 of rectangular shape. Flexible metal plates 3 are vulcanized to the sides of the member I and the ends of these metal plates are bent over the upper end of the member l and overlap, the lower ends of the plates being connected together by a bight portion 4. Rods pass through the material of the member I adjacent the ends thereof and sectional View through the end portions of the plates 3 and have heads or nuts I at the lower ends engaging the part 4 and nuts 8 at their upper ends for holding the ends of the plates on the bolts. Thus these rods or bolts hold the parts in assembled 5 relation and the lower end of the assemblage tapers slightly downwardly as shown to facilitate placing the device between the cylinders A of a printing press as shownin Figure l, with the metal plates engaging portions of the cylinders. 1 A coupling 9 is embedded in the upper end of the member I and communicates the lower end of a sight gauge shown generally at I0 with the chamber 2 and a valve II is connected with the upper end of the sight gauge to permit air to escape from the gauge when the same is in use. This sight gauge can be of any suitable form though it is shown as including an inner transparent tube I2, a sleeve I3 of rubber or the like and an outer casing I4 of metal or any other suitable material, the scale marks I5 being located on this casing I4 adjacent the slots I6 in said casing I4 and sleeve I3, these slots of course permitting portions of the transparent tube to be seen so that the liquid level can be observed.

A bushing I 1 is embedded in the bottom of the member l and a screw I8 is threaded therein for adjusting the liquid level with respect to the zero mark of the sight gauge.

In order to regulate the distance the body of 30 the device is inserted between two cylinders I provide a channel-shaped member I9 which is formed with the opening 20 therein for the passage of the casing I4 and the holes 2| for the passage of the rods or bolts 6 and a pair of plates 35 22 project from the ends of the channel-shaped member and are adjustably held therein by the screws 23 carried by the channel-shaped member and passes through the slots 24 in the plates. The outer ends of these plates 22 willV engage portions of the cylinders A as shown in Figure 1 and thus limit the downward movement of the body of the device between the cylinders and by adjusting the plates 22 the extent of insertion of the body of the device between the cylinders can be regulated and these adjustable supporting means permit the device to be properly arranged between cylinders of diierent types and sizes.

In using the device, the body thereof is placed 50 between the two cylinders, the plates 22 being properly adjusted to limit the downward movement of the body of the device between the cylinders and the compression of the body by the cylinders will force some of, the liquid from the 55 chamber 2 into the sight gauge and thus the distance between the cylinders can be accurately determined. When the device is being used the valve Il is open to permit the escape of air displaced by the rise of liquid and when the device is not in use the valve should be closed to prevent loss of liquid. By adjusting the screw I8 the level of the liquid can be set at zero on the scale l5 before placing the device in use.

lt is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall Within the scope of the appended claims.

Having described the invention, what is claimed as new iszl. A gauge for measuring the distance between a pair of rollers or cylinders comprising an elongated body of resilient material and having a chamber therein containing liquid, a sight gauge connected with one end of the body for receiving some of the liquid therefrom when the body is compressed and ilexible metal plates connected with the sides of the body for contacting the cylinders.

2. A setting gauge for a pair of cylinders comprising an elongated body of resilient material adapted to be inserted between the cylinders, said body having a chamber therein containing liquid, sight gauge connected with the upper end of the body for receiving sorne of the liquid therel from when the body is compressed, a horizontal channel member connected with the upper end of the body, a pair of plates having portions slidably arranged in the channel of said member, one at each end thereof, said plates having slots therein extending longitudinally thereof and screws passing through the slots into the channel member for holdingI the plates in adjusted position, said plates acting to limit the extent of insertion of the body between the cylinders.

3. A setting gauge for a pair of cylinders comprising an elongated body of resilient material adapted to be inserted between the cylinders, said body having an elongated chamber therein containing liquid, the lower part of the body tapering downwardly, flexible metal plates connected with the sides of the body contacting the cylinders, said plates extending over the tapered portion of the body, a bushing embedded in each end of the body, a screw passing through the lower bushing for adjusting the liquid level in the body, a sight gauge connected with the upper bushing,

said body and the chamber therein being of subu stantially rectangular shape in cross section.

4. A setting gauge for a pair of cylinders comprising an elongated body of resilient material adapted to be inserted between the cylinders, said body having an elongate-d chamber therein containing liquid, a sigh-t gauge connected with the upper end of the body and in communication with the chamber, iiexible metal plates extending along two opposing sides of the body and having their lower ends connected together at the lower end of the body and their upper ends bent over the upper end of the body and bolts passing longitudinally through the walls of the body and through the connected lower ends of the plates and through the bent over upper portions of the plates.
